本教程解释了如何使用 JavaScript 通过用单引号和双引号将字符串括起来来获取字符串中的撇号。

var message = "Hi, Let's start reading if you are free!";
console.log(message);

输出：

"Hi, Let's start reading if you are free!"

假设字符串在字符串中的多个位置有撇号； 我们还能用双引号吗？可以，请看下面的例子。

var message = "I can start reading soon when I'll be free from this project, but it doesn't seem to happen.";
console.log(message);

输出：

"I can start reading soon when I'll be free from this project, but it doesn't seem to happen."

var message = "Hi, Let\'s start reading if you are free!";
console.log(message);

输出：

"Hi, Let's start reading if you are free!"

你可能会想，如果我们使用转义字符，我们可以将字符串用单引号括起来而不影响结果吗？是的当然。

var message = 'Hi, Let\'s start reading if you are free!';
console.log(message);

输出：

"Hi, Let's start reading if you are free!"

我们可以在字符串中任何需要的地方转义撇号。

var message = 'I\'ll start reading soon when I\'ll be free from this project, but it doesn\'t seems to happen.';
console.log(message);

输出：

"I'll start reading soon when I'll be free from this project, but it doesn't seem to happen."
